Title: Process for the production of multi-coloured transparencies or diapositives, especially applicable to cinematograph films
IPC: G03C7/46
Filed: 1929-01-18
Abstract: 306,026. Wahl, K. Feb. 14, 1928, [Convention date]. Colour photographh. - Transparent colour positives are produced from a single negative on a support coated on both sides with a non-silver sensitizing material capable of being differentially hardened, for example, bichromated colloid. According to one method, the film is exposed on one side to a negative and the other side to a positive made from said negative, printing being in register and a light absorbing intermediate layer being provided to prevent penetration of the copying light. Each side is then coloured separately. With a black and white negative, a two colour positive is obtained. With a halftone negative blends of colours are obtainable where the half-tones overlap. In a modified process, the negative and or positive for printing may be differentially hardened colloid images independently obtained from a single original negative. In the Specification as open to inspection under Sect. 91 (3) (a) colour negatives or positives therefrom or selections of these may be used for printing on opposite sides. This subject-matter does not appear in the Specification as accepted.
Patent GB-489989-A (GB)
Title: Improvements in and relating to continuous gauges
IPC: A47C4/24
Filed: 1938-01-20
Abstract: 489,989. Linear - dimension gauges. NILES - BEMENT - POND CO. Jan. 20, 1938, No. 1890. Convention date, Aug. 3, 1937. Addition to 479,656. [Class 106 (ii)] Relates to the kind in which the work is adapted to be passed between two workengaging rollers mounted on the body and on a relatively moving member respectively, the relative movement being indicated by an indicator controlled by a movable armature adapted to be actuated by a rotatable rod or spindle, a micrometer device being provided for setting the gauge to standard thickness ; and consists in providing a rotatable member in addition to the rod in screwthreaded engagement with the relatively moving member, both of which are simultaneously rotated to adjust the rod. Similar rollers 18, 19 are carried by a vertically sliding member 16 and by the frame 10. Within the member 16 is secured a nut 20 with which engages a micrometer screw 21 the lower end of which contacts an armature 22 pivoting by a strip 25. Disposed on each side of the armature are induction coils 26. Threaded plugs 30 are provided for adjusting the coils 26 and for adjusting a screw stop 28 for the armature. The upper end of the micrometer screw 21 has secured thereto a gear 32 in mesh with gear teeth on a vertical shaft 33. A counter 37 is driven through bevel gears 35, 36 from this shaft and registers in thousandths of an inch the exact spacing of the roller 18 above the roller 19. Also on the shaft 33 is a second set of teeth meshing with a gear 40 the hub 41 of which is threaded on an intermediate portion of the member 16. The effect of rotating the two gears 32, 40 is to raise or lower the member 16. The threads of screw 21 and the member 16 have the same lead and hand. The hub 41 bears on the fixed member 23 so that rotation of the hub raises or lowers the member 16 without affecting the axial position of the spindle 21. In zero position with the rolls 18, 19 touching the hub 41 will be raised slightly above the surface of the member 23 a distance equivalent to a full upward movement of the armature 24 from a neutral zero indicating position towards the upper coil 26. During the rotation of shaft 33, the hub 41 will first be moved down to engage the member 23 and the spindle 21 a corresponding amount before a lifting movement is applied to member 16. When the device is set, the armature will be raised and the electrical indicator read below standard. When work is inserted the hub 41 and spindle 21 are raised permitting the armature to assume neutral position. A spring 44 normally forces hub 41 and member 16 upwards while an adjustable spring 47 forces them downwards with a greater pressure. A flexible diaphragm 50 keeps out steam, water or dust. In use, the disc 34 is rotated until counter 37 indicates the number of thousandths of an inch in thickness desired in the material gauged. The head 10 is supported by link from a slide as described in the parent Specification.

Abstract: 435,309. Making composite metal strips. ARNOLD, C., 11, Southampton Buildings, Chancery Lane, London.-(Cleveland Graphite Bronze Co. ; 880, East 72nd Street, Cleveland, Ohio, U.S.A.) Jan. 19, 1934, No. 1997. [Classes 83 (i) and 83 (ii)] A strip 11 which may be of steel is passed through a bath of molten coating metal, especially of Babbitt-metal in the manufacture of bearings, and is withdrawn through a die opening 26, molten metal being removed from the lower side by a scraper 33. The strip 11 which is preferably tinned and roughened on its upper surface, passes between a block 23 and plate 24 where it is heated by a burner 27 to approximately the temperature of the molten metal. It is then passed through the bath 14 of molten metal heated by burners 18, 19 and through the opening 26 where the coating metal 10 is caused to congeal by cooling water in a passage 44, and is again cooled on leaving the machine by a jet 46 of water and air. The strip is guided in its passage through the bath 14 in grooves 21 in side pieces 22. The strip is held against the scraper 33 by a member 36, 38 held down by springs 39. Molten metal is delivered to the machine from a melting-pot 47 through a channel 53 by a rotary impeller 51, and a constant level is maintained by means of the overflow outlet 50. A flux or deoxidizing agents such as sal-ammoniac or charcoal may be added to the metal in the vessel 47. In a modification a block 25 which is shorter than that illustrated and is not water-cooled is employed, and the composite strip after leaving the machine and being cooled is further treated in a drawing-die.

Title: Improvements in and relating to reinforced clay articles
Inventor: ASTBURY NORMAN FREDERICK
IPC: C04B28/00
Filed: 1964-01-17
Abstract: <PICT:1074191/C1/1> A structural element made of clay contains metal reinforcement units which are so shaped as to provide portions extending in a generally longitudinal direction of the element and portions extending generally transverse of the element and organized so that tensile stresses are not transmitted from one reinforcing unit to another directly but through the medium of intervening clay. As shown the reinforcing units are links in a chain 11 embedded in a clay column 10.  Insofar the links of the chain are separated by clay at 10a, a tensile force on the column compresses the clay at 10a.  In another embodiment, Fig. 3 (not shown), the reinforcement units are formed by randomly arranged channel-shaped metallic inclusions. The reinforcement units may be fed into the clay column in a rolling operating, during extrusion of the clay through a die or during any other moulding or pressing operation. The reinforcement units may be inserted when the clay is plastic or in the form of dust.  The reinforcement units may be of such section as S or Z.

Title: Improvements in variable speed polyphase motors
IPC: H02K27/06
Filed: 1945-01-26
Abstract: 584,831. A.C. commutator machines. BRITISH THOMSONHOUSTON CO., Ltd., and MAGGS, A. H. Jan. 26, 1945, No. 2120. [Class 35] In a variable speed A.C. commutator motor having an unbalanced polyphase stator winding producing an elliptical rotating field, the speed variation is achieved by movement of the axis of the shortcircuited brushes. In a two-phase motor, Fig. 1, the main phase 5 has fewer turns of heavier wire than phase 6 so that the flux has major and minor axes 10, 11 respectively. Movement of the brushes 2, 3 from the major towards the minor axis reduces the speed through synchronism. In Fig. 3 (not shown) a three-phase modification is shown in which the unbalanced phase is coincident with the minor axis and has an increased number of turns.

Title: Improved production of unsaturated alcohols and/or unsaturated esters
IPC: C07C33/025
Filed: 1942-02-18
Abstract: Unsaturated alcohols and esters are obtained by hydrogenation without a catalyst of an unsaturated carboxylate of lead or cadmium.  When a hydroxy-carboxylate is used, the product is a dihydric alcohol or its ester.  Carboxylates of several metals, at least one of which is lead or cadmium, may be used, and result in different yields and different proportions of alcohols and esters; thus lead carboxylates yield principally alcohols and cadmium carboxylates, principally esters, while mixed carboxylates of cadmium and copper or cadmium and nickel yield principally alcohols.  Examples describe the reduction with hydrogen of lead oleate, cadmium oleate, lead salts of castor oil acids, mixed cadmium and chromium oleates, mixed cadmium and nickel oleates, and lead benzoate.  Specification 562,609 is referred to. Reference has been directed by the Comptroller to Specification 484,995.
